Genes specific to the X chromosome are among newly identified genes linked to rheumatoid arthritis and could help explain why women are more likely than men to develop the disease

Women have two X chromosomes while men have an X and a Y chromosome. The X-chromosome-specific genes were among 14 newly identified genes in both women and men that can lead to rheumatoid arthritis, adding to the 32 genes previously pinpointed by researchers. It is believed that these 46 genes account for the vast majority of genes associated with rheumatoid arthritis. The research could lead to new treatments for the disease.
